What are the three pedals of a car?

The three pedals of a car are the accelerator pedal, the brake pedal and the parking brake pedal. The following is the introduction of the three pedals of the car: 1. The main function of the accelerator pedal is to control the opening of the engine accelerator, so as to control the power output of the engine. 2. The brake pedal, as the name implies, is the pedal that limits power, that is, the pedal for foot braking (driving braking). The brake pedal is used to slow down and stop. 3. The parking brake pedal usually refers to the manual brake installed on the motor vehicle, which is used to stabilize the vehicle after the vehicle stops and avoid accidents caused by skidding when the vehicle stops on the sloping road.
